Excavating contractors typically are private business owners who are regarded as contractors since the actual work is usually only part of a bigger project. In a typical construction project, an excavating contractor appears only after the initial surveying is completed which determines the boundary of the new site. The project manager then assigns the excavating contractor to perform the final survey for the proposed site to determine if the land is acceptable. This is usually when the actual excavation begins.
When the excavation has just begun, it is important to have the excavating contractor to clear the area. This is usually done using heavy equipment such as backhoes, bulldozers, cranes and dump trucks. Excavation can cause the homeowner damage if the foundation is not properly supported. Once the foundation is secure, the excavating contractor will pour the soil of the area where the new driveway or pool will be laid. This process of excavation and soil filling is referred to as foundation clearing. It is the contractor’s job to remove all the excess dirt in a systematic and controlled manner.
After the foundation is cleared, the excavating contractor will dig the required number of trenches for the new driveway or pool. Usually, three trenches are required for underground pools. The length of these trenches must be at least two to three feet. After the holes are dug, the contractor will pour the material needed for the pipes, drainage and gas lines. The holes will be plugged with dirt and tamped flat before the contractor sets about the next task.
Another important job for the excavating contractor is grading. This is used to level and prepare the area for any future construction projects. This is also done in case there are no utilities in the area. Grading is divided into two different types: house-raising and public road grading. For house-raising, excavating is done by machine while public road grading involves manual labor. These two types of grading are usually done on construction sites by separate companies.
While working in residential areas, excavation contractors may need to clear driveways, sidewalks, alleys, curbs, docks and pools. They may also be called upon to remove tree roots that may hinder the way. There are some instances when contractors have to clear away debris and rubbish accumulated during the cleaning process. These include street repair and landscaping. For example, a construction project may require clearing away a sidewalk and crosswalk after a renovation. Construction workers may need to clear away old wood boards that are not in use, empty lot or vacant lots.
One of the most difficult tasks excavating contractors have to undertake is water pipes and electrical wiring. If they do not clear the area properly, leaks can occur and pose a threat to the people living in the vicinity. For this reason, a regular schedule of clearing away debris has to be made. Water pipes are excavated using a machine while electrical wires are manually dug using a wire cutter. All the excavating contractor has to do is call a reliable water pipes and electric surveying crew to do the job.
